The figure of the part ' s original shape depend on digital equinpent mostly . digital equiment is divided into two big types , contac ttype and uncontact tyope . the contact type decelop with the optical and electonic element applied widely . uncontact measurement is rapid . the measured part is not scared , but it requirethat the measured part ' s surface can glisten . cmm is typical delegate of contact measurementcomparing to uncontact measurement , cmm is slow , but it has upper measurement precision . in range of required figure precision , it will affact the selective way of moddfile cuver 由于其测量过程是利用光学方法进行的，从而对被测物体的表面提出了一定的要求，表面反光或全黑的物体都不适合于光学方法进行测量，或者说当遇到这样的被测物体时需要更复杂的光学技术来保证测量的顺利进行。坐标测量机( coordinatemeasuringmachine , cmm )是接触式数字化设备的典型代表。和非接触测量方法相比， cmm虽然在数字化速度上比较低，但是它具有较高的测量精度。
